Product Monday: 3- & 5-Channel Drivers For Tunable Arrays

The ORB3 and ORB5 LED drivers from Arkalumen offer intelligent tunable spectra control within compact Zhaga-standard dimensions. These drivers are designed to provide lighting designers and fixture developers with greater flexibility through their modular architecture, enabling a wide range of customizations for various lighting applications.

Product Overview

The ORB family includes two main models:

• ORB3: A 3-channel driver for tunable white lighting.
• ORB5: A 5-channel driver for tunable color lighting.

Both models feature a 50mm diameter and 8mm height, making them ultra-compact. They integrate multi-channel constant current drivers with up to five controlled output channels. The ORBs also include holders for tunable LED modules (white or color) and platforms for mounting TIR optics and reflectors, enhancing compatibility with various lighting designs.

Customization Features

The modular design allows users to:

• Select tunable LED arrays to achieve specific spectra mixes, light-emitting surface (LES) sizes, and lumen outputs.
• Choose control protocols such as 0-10V, DMX/RDM, Casambi BLE, or Silvair BLE.
• Utilize auto-calibration for simplified programming or customize settings like intensity levels, CCT mappings, and dim curves using Arkalumen’s APT Programmer.

Key Specifications

• Control Protocols: Options include wired (0-10V, DMX/RDM) and wireless (Casambi BLE, Silvair BLE).
• Form Factor: Zhaga standard dimensions ensure easy integration into existing systems.
• Performance: Supports up to 48W power input and maximum total current of 2000mA. The ORB5 divides current across its five channels (500mA for three channels and 1000mA for two), while the ORB3 supports uniform channel currents of up to 1000mA.

Applications

The ORB systems are ideal for:

• Downlights
• Spotlights
• Landscape lighting

Their compact size and intelligent features make them suitable for both residential and commercial environments.

Additional Features

The ORB drivers are designed for integration with Arkalumen’s ecosystem of diffuser elements, TIR optics, and reflectors. They also feature embedded antennas for wireless communication, ensuring good range without interference from nearby metal objects.
